Dear list I apologise if this is a really simple question but it has me stumped! I should add that i am a relative newcomer to MapInfo. My question is: Short version :How do I carry out a UNION (Arc/Info) in MapInfo. Long Version: My problem is that i have to layers: a) a Postcode Boundary table (Posctode), and b) a Ward boundary table (Ward). What I want to do is create a new layer with (to use an ArcInfo command) the two layers UNION'ed. The idea is then to carry out a count of each household in each new area by Point in polygon analysis of my address list. I have tried: SQL select where Postcodes.obj Intersects Ward.obj. This returns a layer which looks identical to the postcode layer. I had presumed that it would show both layers intersected. However when i use Identify it shows the correct number of wards per postcode, but to make things interesting, when i examine the browser, it shows only 1 ward. Just for fun i carried out another SQL to find out which households were in which area only to find that my total household number had increased six fold....... Any ideas....??? Am I breaking all the rules of good GIS practice?? TIA Jon Bloor. -- This message is confidential. It may also be legally privileged.
